| 摘 要： | 作者应用１９４９～１９９４年中国洪水灾情资料，重构了其嵌入相空间序列，探讨了其时序的分形特征，计算得到了分维数。研究表明：洪水灾害成灾面积的时序分布具有分形特征。研究结果为建立洪水灾害成灾面积的时序预测预报模型提供依据。

| Abstract: | In this paper,based on the statistical data on the effects of flood disasters occurred in China from 1949 to 1994,the time series imbedding space is rebuilt and the time series fractal characteristics is investigated.The experimental results show that the temporal distribution of inundated area of flood disaster has fractal characteristics.The obtained conclusions will provide a scientific basis for establishing the forecast model of inundated area of flood disaster. |
